Wait a minute, someone explain it to me..so...
!?!?the devola and popola models in this game ARE THE ORIGINAL FROM THE TIME OF THE LEGION!!?!?!?
No. There were a large number amount of twin units created to observe Project Gestalt in different cities. The androids Devola and Popola from the original Nier are long dead.
So I finished it and obtained Ending E. I enjoyed it overall, but I did find the story to be quite confusing at times, which I believe was intentionally so. If Taro moves on with the franchise I hope he decides to create an equally disturbing story, but at a much easier level to understand. The original Nier was not complicated at all. Neither was Drakengard 1 or 3.
